Australian equities opened higher on Monday, with the S&P/ASX 200 index climbing 0.2% to 8,809.8.
The benchmark index found support from the energy sector, which rallied as investors priced in fresh supply disruption risks stemming from intensifying military conflict between the United States and Iran.
Energy stocks led the advance, with Woodside Energy Group (NST.AX) and Santos (EVN.AX) among the top performers.
The sector's strength offset weakness elsewhere in the market, as traders weighed the potential for tighter global oil supplies against broader economic uncertainty.
Brent crude futures rose in early trading, reflecting the market's assessment of the geopolitical threat to key shipping routes.
The rally marks a shift from recent sessions, where Australian equities had been driven by broad-based strength in financials and technology.
